SPECIFICATION forming part of Letters Patent No. 326,082,dated September8, 1885.

Application filed January 29, 1885. (No model.)

.To all w71 om it' may concern:

Be it known that I, MILTON W. HAZELTON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Feed-Water Heaters and Puriers,of which the following is a specification, reference being had to the'accompanying drawing, forming a part thereof, which represents asectional elevation and plan View of my improved device.

The present invention relates to that class of devices in which thetemperature of the feed-Water is elevated by contact with livesteam andcleared of its impurities; and it consists in a special construction andinternal arrangement of the parts, which'I will rst proceed to describe,but subsequently to define in the claim.

In the drawing, A represents the shell of the heater and purifier,generally made in cylindrical form, and provided with a steam-inlet, a,Water-inlet b, water exit or delivery c, and a discharge or blow-offpipe, d.

B represents the steam-chamber, partially filled with coke or similarsubstance. B a separated filtering-chamber containing any suitablefiltering material, and C a settlingchamber, that communicates with thechambers B B through a perforated diaphragm. The water-inlet pipe b isextended into the upper part of the steam`chamber B, and provided withbranch pipes or nozzles .c d, each being iitted with aperforated cap, s,as shown.

The steamchamber B is partially lled with coke or similar substance, andthe filteringchamber B contains any suitable filtering material. Thefeed-water is forced through the pipe b and discharged vertically in theform of spray or jets that impinge against the adjacent end of theshell, which further separates the divided spray and facilitates itselevation in temperature by contact withthe admitted steam. The watergravitates through the chamber B in a` divided and heated state to thesettling-chamber C, and rises in the iiltering-chamber B to the level ofthe delivery-pipe c. Such portion of the impurities that is notdeposited on the surfaces of the lumps of coke in the chamber B willfind its Way to the settling-chamber C, and if carried by entrainmentinto the filtering-chamber B', it is still further arrested by thefiltering material in the chamber B', that extends to the final exit ofthe water from the device.

The respective pipeconnections are provided with the usual cocks orvalves for regulating the steam and water supply and blowoff, andsuitable man and hand holes are also provided for the introduction ofthe coke and filtering material, and for cleaning and repairs, all ofwhich will be readily understood by an inspection of thedrawing.

Having thus fully described my invention, what I claim, and desire tosecure by Letters Patent, is- Y In a feed-water heater and puritier,thecombination of a steam-chamber partially filled with lumps of coke orsimilar substance, a separated ilteringchamber containing snitablefiltering material, and a connecting settling-chamber located beneathand adjacent to both, substantially as set forth.

MILTON W. HAZELTON.
